As emotions reflect our moral beliefs and principles, they can guide our interpersonal actions and decisions in meaningful ways. For example, feelings of disgust motivate the rejection of people violating our key values (Rozin, Haidt, & McCauley, 2000). Accordingly, recent developments in the study of morality suggest that disgust may play an important role in moral judgments and decision making (e.g., Greene, Sommerville, Nystrom, Darley, & Cohen, 2001; Haidt, 2001). However, sometimes the influences of emotions on our decisions are less straightforward. Indeed, emotions often arise due to the presence of arbitrary factors, such as the weather (Simonsohn, 2009) or having watched a sad movie (Forgas, 1994). Features of the situation that have little or nothing to do with someone’s moral beliefs may induce an emotion, and this emotion can exert an influence on subse-quent behavior (for reviews, see Clore & Huntsinger, 2007; Forgas, 1995; Pizarro, 2000). Indeed, unrelated feelings of disgust (i.e., aroused by an odor or a filthy desk) can result in a stronger rejection of a moral transgression (e.g., Schnall, Haidt, Clore, & Jordan, 2008; Wheatley & Haidt, 2005). Accordingly, unrelated disgust influences may bring forth aversive consequences for interpersonal behavior (e.g., social exclusion and severe punishment). In the current arti-cle, therefore, we investigate when disgust biases our moral judgments and when this is not the case. In doing so, we highlight the involvement of the human attention system as a possible moderator. One reason why disgust may have such an impact on peo-ple’s moral judgments is the strong influence of emotions on information processing. Attention is quick and frequently is directed in unintentional ways to affective information in the environment (Bradley, 2009). Furthermore, once emotional information has captured attention, this may trigger emotion
